The most important feature to capture for Ipomoea hederifolia to differentiate from Ipomoea coccinea is the calyx of the fruit in various stages... The leaves on both Ipomoea hederifolia and Ipomoea coccinea can mimic each other ( I know because I have grown enough of them myself) but the pedicels of Ipomoea hederifolia always remain erect while the pedicels of Ipomoea coccinea reflex... So, in my experience trying to differentiate Ipomoea hederifolia from Ipomoea coccinea using any other part except the calyx and pedicel will lead you astray... regards, Ron
